ORE-CONCENTRATOR.

SPECIFICATION forming part of Letters Patent No. 487,523, dated December 6, 1892. Application filed March 11, 1892. serial No- 424.533- (No model.)

To all whom it may concern.-

Be it known that I, ALFRED GONZALEZ, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Ore-Concentrators; and I do hereby declare the following to be a full, clear, and exact description of said invention, such as will enable others skilled in the art to which it most nearly appertains to make, use, and practice the same.

My invention has relation to certain'new and useful improvements in ore-concentrators; and it consists in the arrangement of parts and details of construction, as will be hereinafter more fully set forth in the drawings and described and pointed out in the specification.

My invention relates more particularly to mechanism for imparting a compound longitudinal and reciprocating motion to the concentrating-frame, in allowing for an independent speed-regulation of the traveling belt and concentrating-frame, and, further, in allowing a reverse throw to be imparted to the concentrating-frame, so as to overcome banking of material to one side thereof, without necessitating stoppage of the machine.

Referring to the drawings forming a part of this application, wherein similar letters of reference denote corresponding parts throughout the entire specification and severalviews, Figure 1 is a side elevation of the concentrator; Fig. 2, a front end elevation, and Fig. 3 a top plan view partly broken away.

The letter A is used to indicate the side pieces of my machine, which are united by end and front cross-plates A A which constitutes the main frame of the concentrator. Upon this frame is supported the conoentrating-frame B through the medium of springsupports B in the usual manner. The rear end of said frame is movably connected to end plate A by means of pin a, which works in a slot formed in said plate and allows of longitudinal movement of the frame B. Within this frame and over rolls O 0, working within bearings in said frame, and roll C rotates the belt E, which is rotated through the medium of the hereinafter-described mechanism. From front plate A depend supporting brackets or arms E, through which works operating shaft E To one end of said shaft is secured pulley-wheel E while to the opposite end is fastened disk-wheel E Between inner supporting brackets or arms are located frictional rollers F F, which are movably secured upon operating shaft E Fig. 2. These rollers are connected together by means of rack-plate F Rigidly connected to plate A in any suitable manner is plate or strap G, within which is suspended cog-wheel g, adapted to engage teeth of rack-plate F This wheel is rotated by means of hand-wheel G, and as same is turned from left to right rack-plate is carried or moved in a similar direction. Frictional rollers F F contact with disk-roller H, secured to lower end of vertical shaft H, which works through bearing-box H secured to plate A The upper or projecting portion H is formed eccentric (shown in Fig. 3) and is secured within bearing-box I, attached to'forward end of concentrating-frame B.- Consequently as the vertical shaft rotates an oscillating motion is imparted to the forward end of concentrating-frame. The frictional rollers F F, while being movable upon shaft E move longitudinally upon shaft-key e, and consequently revolve in unison therewith. The connecting raek-plate F does not rigidly connect the frictional rollers, but isloosely connected thereto, so as to allow of free rotation thereof without imparting motion to said plate or bar. As one of said frictional rollers is moved into contact with disk-roller H rotary motion thereof is imparted thereto, consequently rotating vertical shaft H and imparting throw to the concentrating-frame. As the frictional roller is moved from center to periphery of disk-roller H or from periphery to center a faster or slower rotation is given vertical shaft H. Consequently there is imparted a quick or slow motion to concentrating-frame, as the ore to be concentrated may require.

Inasmuch as the constant vibration or movement of concentrating-frame in one direction tends to bank the material to one side, I have so constructed myv mechanism as to permit of a reverse motion to be imparted to the frame. This is accomplished by rotating cog-wheel g,

so as to throw one of the frictional wheels out of contact with disk-roller and moving the opposite one in. It will thus be observed that a throw may be imparted from right to left, or vice versa, as required, consequently.

overcoming banking of the material.

Disk-wheel E secured upon outer end of operating-shaft, contacts with and imparts motion to roller J, secured to shaft J, which works in bearings jj of bracket K, projecting forwardly from side pieces A of the frame. Thus with rotation of disk-wheel E motion is imparted to shaft J through the medium of roller J. The forward or upper end J of shaft J works in bearing formed in bracket K and has secured thereto bevel gear-wheel L, which rotates therewith. Said gear meshes with gear L, secured to worm-shaft L which works in upper bearing of bracket K. This worm-shaft meshes with teeth of Wheel M, which is mounted upon outer end of axle m of belt-roll 0'. Consequently as worm-shaft is rotated through the medium of before-described bevelgears the motion thereof is im parted to wheel M and by same is transmitted to belt-r0110, and thus serves to give motion to concentrating-belt. Inasmuch as bracket K is attached to the concentrating-frame, which is continually moving, as before described, it is obvious in order to maintain gears L and L (which are secured to shafts working in bearings of said brackets) in mesh with each other a flexible connection be made between shaft J and upper end J Consequently I form the intermediate portion of spring-rod M. It will be understood that portions J, M, and J constitute a whole, and the expression flexible shaft as hereinafter used is in tended as covering these parts as an entirety. By means of screw-wheel N, which works upon lower end of flexible shaft, I am enabled to raise or lower same within its bearings, and inasmuch as with such movement roller J is carried in or out upon face of disk roller or wheel a slower or faster rotation will be given said shaft, consequently imparting a rapid or slow travel to concentrating-belt. By this arrangement it will be observed that the movement of concentratingframe and travel of concentrating-belt may be regulated independent of each other. Thusa rapid travel may be given the belt and slow motion imparted to the frame, and vice versa.

Having thus described my invention, what I claim as new, and desire to secure protection in by Letters Patent of the United States, 1s

1. In an ore-concentrator, the combination, with the movable concentrating-frame, of the eccentric vertical shaft, disk-roller secured thereto, operating-shaft working in bearings of front plate, frictional rollers movably secured upon said shaft, and mechanism for throwing said rollers alternatively in or out of contact with the disk-roller, so as to reverse the movement of the concentrating-frame and to increase or decrease the same, as and for the purpose set forth.

2. In an ore-concentrator, the combination, with the movable concentrating-frame and the endless concentrating-belt, of the vertical eccentric shaft provided with a disk-roller, operating-shaft, frictional rollers movably secured upon said shaft, mechanism for moving the rollers alternatively in or out of contact with disk roller or plate of vertical shaft, and independent mechanism receiving motion from operating-shaft in order to impart travel to concentrating-belt, as and for the purpose set forth.

3. In an ore-concentrator, the combination, with the concentrating-frame, of mechanism for imparting an increased or decreased or reversed movement thereto, the concentrating-belt traveling within said frame, and mechanism for imparting travel thereto and adapted to increase or decrease rotation thereof independent of movement of concentrating-t'rame.

4c. In an ore-concentrator, the combination, with the concentrating-frame and the concentrating-belt, of intermeshing gear-Wheels secured to concentrating-frame, a flexible shaft for imparting motion to said gears and belt-roller, and mechanism for adjusting the said shaft longitudinally, so as to increase or decrease the rotation thereof, as and for the purpose set forth.

5. In an ore-concentrator, the combination, with the concentrating-belt, of the adjustable flexible shaft, gearing between said shaft and the belt, a disk to rotate the said shaft, and means for shifting the shaft diametrically of the disk, so as to vary the rotation of the shaft.
